The Grove - Temperature Sensor uses a Thermistor to detect the ambient temperature. The resistance of a thermistor will increase when the ambient temperature decreases. It's this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor is ºC, and the accuracy is ±1.5ºC Grove - Temperature Sensor Thermistor: 온도에 따라 전기 저항치가 달라지는 반도체 회로 소자 오늘 배울 내용 1. 시리얼통신 2. 온도센서에서 Analog 신호 입력 (Input) 및 온도 계산 3. 온도에 따라 피에조 부저 출력 (Output, PWM) 피에조 부저는 +/- 방향성 없음.
